Macula-involved rhegmatogenous retinal detachment (RRD) is a condition that can cause severe central visual disturbance, even after successful retinal re-attachment. Optical coherence tomography angiography (OCTA) can measure vessel density (VD) in the macular capillary plexus (MCP), both superficially (the SCP) and deeply (the DCP), and can measure the foveal avascular zone (FAZ) in these layers. Previous research used OCTA to evaluate the correlation between the FAZ and visual acuity (VA) in the eyes with macula-off RRD [1]. Here, we extend previous results by including measurements of OCTA-measured VD in both the SCP and DCP, and compared these measurements with other clinical findings, including VA and foveal thickness (FT), in order to investigate in greater detail the significance of vascular changes in the eyes with successfully re-attached macula-off RRD.
